Rapid-Fire Cyclones over the North Indian Ocean

With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both Chapala and Patricia.

The Taj Mahal. You can see its enormous size from the line of people waiting to get inside standing on the pedestal. The line completely circled the tomb on this holiday weekend.

Bangladesh and India, Too

Returning to Bangladesh for additional fieldwork, I stopped off in India for several meetings, but we found time for some sightseeing, too. We were able to see the Qutub Minar complex in Delhi as well as the Taj Mahal and Agra Fort in Agra. Plus all the meetings in Delhi, Kolkata and Dhaka were very successful.
